18 = 3x6 = x
3x6, 9x2, 18x1,
To solve the equation n + 3x6 = 30, first calculate 3x6, which equals 18. Then subtract 18 from both sides of the equation to isolate n. Thus, n = 30 - 18, which simplifies to n = 12.
-3x6-25 is equal to -43
Well, isn't that a lovely question! To cover 15 square feet with 3x6 tiles, you would need 30 tiles. You see, each tile covers 0.5 square feet, so by dividing 15 by 0.5, you get 30 tiles. Happy tiling, my friend!
